Systems and methods for supporting secure transfer of data between workspaces

ABSTRACT

Systems and methods support secure transfer of data between workspaces operating on an IHS (Information Handling System). Upon a request for access to a first managed resource, such as protected data, a first workspace is deployed according to a first workspace definition. Upon a request for access to a second managed resource, a second workspace is deployed according to a second workspace definition. In response to an indication of a portion of the protected data from the first workspace being copied to a buffer supported by the IHS and of a request to paste the copied portion of the protected data to the second workspace, the protections provided by the second workspace are evaluated. If the protections of the second workspace are inadequate, an updated second workspace definition is selected that specifies additional protections. The second workspace is updated according to the updated second workspace definition and the transfer is permitted.

FIELD

This disclosure relates generally to Information Handling Systems (IHSs), and, more specifically, to systems and methods for computing environments utilized by IHSs.

BACKGROUND

As the value and use of information continue to increase, individuals and businesses seek additional ways to process and store information. One option is an Information Handling System (IHS). An IHS generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes. Because technology and information handling needs and requirements may vary between different applications, IHSs may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in IHSs allow for IHSs to be general or configured for a specific user or a for specific use such as financial transaction processing, airline reservations, enterprise data storage, global communications, etc. In addition, IHSs may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

IHSs provide users with capabilities for accessing, creating, and manipulating data, and often implement a variety of security protocols in order to protect this data. Historically, IHSs have been designed to implement security paradigms that isolate them from possible security threats, much like a castle is designed and constructed to safeguard persons within its walls. In the case of a network of IHSs, for example, security systems implement strategies that isolate the entire network from threats. In effect, a set of castle walls is constructed around the entire network. While working from within the walls of such systems, users may be provided with secure and productive use of data.

However, security paradigms that isolate protected data within the walls of a castle are increasingly frustrated by the realities of modern computing. Nowadays, users expect to access protected data using a plethora of different IHSs while located at a variety of physical locations. In an effort to leverage the security of the system providing access to the data, current protocols for supporting remote access have sought to extend the defenses of the system to remote IHSs, essentially extending the castle walls to temporarily include all or part of the remote IHSs.

Another complication of modern computing is the user's expectation that they will be able utilize their own personal IHSs to access some or all of their protected data, even if those users are provided with enterprise-issued IHSs for accessing it. For administrators of such systems, this increases the difficulty in securing all manners in which protected data may be accessed. This difficulty is greatly expanded by the need to support access to protected data using an ever-growing list of software applications, whether on a personal IHS or an enterprise-issued IHS. Moreover, the administration of such systems is further complicated by the need to support access to protected data from a variety of physical locations and via a variety of networks, including untrusted networks. Faced with such problems, systems for providing access to protected data are often burdensome to administer and ultimately the data is insufficiently protected so as to facilitate its productive use.

A known technique for securing access to protected data accessed via an IHS is to isolate the data within a segregated or virtualization environment that runs on the IHS using a virtual machine or container. Conventional types of virtualization environments provide varying degrees of isolation from the hardware and operating system of the IHS. However, similarly to the castle wall defenses of security paradigms that seek to isolate protected data within a secure perimeter, conventional virtualization environments are also ill-suited to modern computing. Particularly, these virtualization techniques establish an isolated computing environment on an IHS that allows a user to access only data and applications approved for that user.

In some instances, conventional virtualization techniques may determine the data, applications, and protections to be provided by on an IHS based solely on the identity of the user, and therefore tend to implement all security protocols that would be necessary to secure access to all approved data and applications. As the inventors hereof have recognized, however, not only does this result in complex virtualization efforts that consume large portions of the memory and processing capabilities of the IHS, but conventional techniques also do not account for what the user actually intends to do while operating the IHS.

As the inventors hereof have further recognized, modern computing ought to provide users with access to protected data via a variety of IHSs and at practically any location. Yet conventional virtualization fails to account for the specific context in which an IHS is being used during a particular session, much less to account for changes to the context in which an IHS is used during a session. Furthermore, conventional virtualization techniques tend to provide support for many capabilities that are not actually used. The overhead required to provide such unnecessary capabilities unduly burdens the operation of an IHS and degrades productivity and user experience.

DETAILED DESCRIPTION

For purposes of this disclosure, an IHS may include any instrumentality or aggregate of instrumentalities operable to compute, calculate, determine, classify, process, transmit, receive, retrieve, originate, switch, store, display, communicate, manifest, detect, record, reproduce, handle, or utilize any form of information, intelligence, or data for business, scientific, control, or other purposes. For example, an IHS may be a personal computer (e.g., desktop or laptop), tablet computer, mobile device (e.g., Personal Digital Assistant (PDA) or smart phone), server (e.g., blade server or rack server), a network storage device, or any other suitable device and may vary in size, shape, performance, functionality, and price. An example of an IHS is described in more detail below. FIG. 1 shows various internal components of an IHS configured to implement certain of the described embodiments. It should be appreciated that although certain embodiments described herein may be discussed in the context of a personal computing device, other embodiments may utilize various other types of IHSs.

FIG. 1 is a diagram depicting components of an example IHS 100 configured to support secure transfer of data between workspaces operating on the IHS 100. In some embodiments, IHS 100 may be employed to instantiate, manage, and/or terminate a workspace that may be a secure environment that may provide the user of IHS 100 with access to managed resources, such as protected enterprise data, while isolating the protected data from the operating system (OS) and other applications executed by IHS 100. In some embodiments, the construction of a workspace for a particular purpose and for use in a particular context may be orchestrated remotely from the IHS 100 by a workspace orchestration services, such as described with regard to FIGS. 2 and 3. In some embodiments, portions of the workspace orchestration may be performed locally on IHS 100 in conjunction with operations by a remote workspace orchestration service. IHS 100 may be configured with program instructions that, upon execution, cause IHS 100 to perform one or more of the various operations disclosed herein. In some embodiments, IHS 100 may be an element of an enterprise system that may include any number of similarly configured IHSs in network communications with each other.

As shown in FIG. 1, IHS 100 includes one or more processor(s) 101, such as a Central Processing Unit (CPU), operable for executing instructions retrieved from system memory 105. Although IHS 100 is illustrated with a single processor, other embodiments may include two or more processors, that may each be configured identically, or to provide specialized processing functions. Processor(s) 101 may include any processor capable of executing program instructions, such as an INTEL PENTIUM series processor or any general-purpose or embedded processors implementing any of a variety of Instruction Set Architectures (ISAs), such as the x86, POWERPC®, ARM®, SPARC®, or MIPS® ISAs, or any other suitable ISA. In the embodiment of FIG. 1, processor(s) 101 includes an integrated memory controller 118 that may be implemented directly within the circuitry of the processor(s) 101, or memory controller 118 may be a separate integrated circuit that is located on the same die as processor(s) 101. Memory controller 118 may be configured to manage the transfer of data to and from system memory 105 of IHS 100 via high-speed memory interface 104.

In some embodiments, system memory 105 may include portions that have been designated for exclusive use by workspace operations such as described herein, thus providing an isolated memory for the operation of workspaces. As described in additional detail with regard to FIGS. 3 and 4, IHS 100 may be configured to provide a user with access to managed resources via one or more workspaces that may operate in various degrees of isolation from the hardware and software of IHS 100 and from each other. In certain instances, portions of system memory 105 dedicated for use in support of workspaces may be further divided into portions that are each dedicated for use in the operation of a specific workspace, thus providing an isolated memory for the operation of each individual workspace hosted by IHS 100. In some embodiments, a portion of the system memory 105 may be dedicated for exclusive use as a buffer used to support transfer of data between workspaces, such as described in additional detail with regard to FIG. 4.

System memory 105 that is coupled to processor(s) 101 via memory bus 104 provides processor(s) 101 with a high-speed memory that may be used in the execution of computer program instructions by processor(s) 101. Accordingly, system memory 105 may include memory components, such as such as static RAM (SRAM), dynamic RAM (DRAM), NAND Flash memory, suitable for supporting high-speed memory operations by processor(s) 101. In some embodiments, system memory 105 may combine both persistent, non-volatile memory and volatile memory.

In certain embodiments, system memory 105 includes secure storage 120 that may be a portion of the system memory designated for storage of information, such as access policies, component signatures, encryption keys, and other cryptographic information, that may be used in hosting one or more secure workspaces on IHS 100. In some embodiments, a signature may be calculated based on contents of secure storage 120 and stored as a reference signature. The integrity of the data stored in secure storage 120 may then be validated at a later time by recalculating this signature of the contents of the secure storage and comparing the recalculated signature against the reference signature. In some embodiments, the secured memory 120 may include one or more portions that are assigned for exclusive use by workspaces. In such embodiments, these portions of secured memory 120 may be further divided into portions that are each dedicated for use in the operation of a specific workspace. In some embodiments, a portion of the secured memory may be dedicated for exclusive use as a buffer used to support transfer of data between workspaces, such as described in additional detail with regard to FIG. 4.

IHS 100 utilizes chipset 103 that may include one or more integrated circuits that are coupled to processor(s) 101. In the embodiment of FIG. 1, processor(s) 101 is depicted as a component of chipset 103. In other embodiments, all of chipset 103, or portions of chipset 108 may be implemented directly within the integrated circuitry of processor(s) 101. Chipset 103 provides processor(s) 101 with access to a variety of resources accessible via bus 102. In IHS 100, bus 102 is illustrated as a single element. However, other implementations may utilize any number of buses to provide the illustrated pathways served by bus 102.

As illustrated, a variety of resources may be coupled to processor(s) 101 of IHS 100 through chipset 103. For instance, chipset 103 may be coupled to network interface 109, such as provided by a Network Interface Controller (NIC) that is coupled to the IHS 100 and allows the IHS 100 to communicate via a network, such as the Internet or a LAN. Network interface device 109 may provide IHS 100 with wired and/or wireless network connections via a variety of network technologies, such as wireless cellular or mobile networks (CDMA, TDMA, LTE etc.), WIFI and BLUETOOTH. In certain embodiments, network interface 109 may support connections between a trusted IHS component, such as trusted controller 115, and a remote orchestration service. In such embodiments, a connection supported by network interface 109 between the remote orchestration service and the trusted component may be considered an out-of-band (00B) connection that is isolated from the OS of the IHS.

Chipset 102 may also provide access to one or more display device(s) 108 via graphics processor 107. In certain embodiments, graphics processor 107 may be comprised within one or more video or graphics cards or an embedded controller installed as components of the IHS 100. Graphics processor 107 may generate display information and provide the generated information to one or more display device(s) 108 coupled to IHS 100, where display device(s) 108 may include integrated display devices and/or external display devices coupled to IHS, such as via an I/O port 116. In certain embodiments, graphics processor 107 may be integrated within processor 101. The one or more display devices 108 coupled to IHS 100 may utilize LCD, LED, OLED, or other thin film display technologies. Each display device 108 may be capable of touch input such as via a touch controller that may be an embedded component of display device 108, graphics processor 107, or a separate component of IHS 100 accessed via bus 102.

In certain embodiments, chipset 103 may utilize one or more I/O controllers to access hardware components such as user input devices 111 and sensors 112. For instance, I/O controller 110 may provide access to one or more user I/O devices 110 such as a keyboard, mouse, touchpad, touchscreen, microphone, speakers, camera and other input and output devices that may be coupled to IHS 100. User input devices 111 may interface with I/O controller 110 through wired or wireless connections.

Sensors 112 accessed via I/O controllers 110 may provide access to data describing environmental and operating conditions of IHS 100 (e.g., accelerometers, gyroscopes, hinge sensors, rotation sensors, hall effect sensors, temperature sensors, voltage sensors, current sensors, IR sensors, photosensors, proximity sensors, distance sensors, magnetic sensors, microphones, ultrasonic sensors, etc.).

In some cases, chipset 103 may include a sensor hub capable of utilizing information collected by sensors 112 in determining the relative orientation and movement of IHS 100. For instance, the sensor hub may utilize inertial movement sensors, that may include accelerometer, gyroscope, and magnetometer sensors, and are capable of determining the current orientation and movement of IHS 100 (e.g., IHS 100 is motionless on a relatively flat surface, IHS 100 is being moved irregularly and is likely in transport, the hinge of IHS 100 is oriented in a vertical direction). In certain embodiments, the sensor hub may also include capabilities for determining a location and movement of IHS 100 based on triangulation of network signal and based on network information provided by the OS or network interface 109. In some embodiments, the sensor hub may support additional sensors, such as optical, infrared and sonar sensors, that may provide support for xR (virtual, augmented, and/or mixed reality) sessions hosted by the IHS 100 and may be used by the sensor hub provide an indication of a user's presence near IHS 100, such as whether a user is present, absent, and/or facing the integrated display 108.

In cases where the end-user is present before IHS 100, the sensor hub may further determine a distance of a user from the IHS, where this determination may be made continuously, at periodic intervals, or upon request. The detected or calculated distances may be used by processor 101 to classify the user as being in the IHS's near-field (user's position<threshold distance A), mid-field (threshold distance A<user's position<threshold distance B, where B>A), or far-field (user's position>threshold distance C, where C>B).

In embodiments where IHS 100 may support multiple physical configurations, such as a convertible laptop, N-in-1 device, or the like, the sensor hub may utilize one or more mode sensors 112 that collect readings that may be used in determining the current posture in which the IHS 100 is physically configured. In certain embodiments, such posture determinations may be additionally made using the movement and orientation information provided by sensors 112. In laptop and convertible laptop embodiments, for example, processor 101 or trusted controller 115 may utilize a lid position sensor 112 to determine the relative angle between the two panels of the laptop in order to determine the mode in which IHS 100 is physically configured. In such embodiments, the lid position sensor may measure the angle of rotation of the hinge that connects the base panel and lid panel of IHS 100. In some embodiments, processor 101 or trusted controller 115 may provide collected lid position information, such as the hinge angle, to the sensor hub for use in determining the posture in which IHS 100 is configured. In some embodiments, the sensor hub may interface directly with the lid position sensor in determining hinge angle information.

The sensor hub may determine the posture of IHS 100 based, at least in part, on the angle of rotation of the hinge of IHS 100 from a closed position. A first range of hinge angles from a closed position may indicate a laptop posture, a second range of hinge angles may indicate a landscape posture and a third range of angles may indicate a tablet posture. The sensor hub may additionally utilize orientation and movement information collected from inertial movement sensors 112 to further determine the posture in which the IHS 100 is physically configured. For instance, if the sensor hub determines that IHS 100 is configured with a hinge angle of a laptop configuration, but IHS 100 is oriented on its side, the IHS may be determined to be in a book mode. If IHS 100 is determined to be tilted such that the hinge is oriented between horizontal and vertical, the user's face is detected to be facing the integrated display, and IHS 100 is experiencing slight movement, the sensor hub may determine that the IHS 100 is being used in a book posture. The sensor hub may determine that IHS 100 is opened to a 180-degree hinge angle and lies on a flat surface, thus indicating that IHS 100 it is being used in a landscape posture. The sensor hub may similarly determine that IHS 100 is in a tent configuration, in response to detecting a hinge angle within a defined range, such as between 300 and 345 degrees, and also detecting an orientation of IHS 100 where the hinge is aligned horizontally and is higher than both of the display panels of IHS 100.

Other components of IHS 100 may include one or more I/O ports 116 for communicating with peripheral external devices as well as various input and output devices. For instance, I/O 116 ports may include HDMI (High-Definition Multimedia Interface) ports for use in connecting external display devices to IHS 100 and USB (Universal Serial Bus) ports, by which a variety of external devices may be coupled to IHS 100. In some embodiments, external devices coupled to IHS 100 via an I/O port 116 may include storage devices that support transfer of data to and from system memory 105 and/or storage devices 119 of IHS 100.

Chipset 103 also provides processor(s) 101 with access to one or more storage devices 119. In various embodiments, storage device 119 may be integral to the IHS 100, or may be external to the IHS 100. In certain embodiments, storage device 119 may be accessed via a storage controller that may be an integrated component of the storage device. Storage device 119 may be implemented using any memory technology allowing IHS 100 to store and retrieve data. For instance, storage device 119 may be a magnetic hard disk storage drive or a solid-state storage drive. In some embodiments, storage device 119 may be a system of storage devices, such as a cloud drive accessible via network interface 109.

As illustrated, IHS 100 also includes BIOS (Basic Input/Output System) 117 that may be stored in a non-volatile memory accessible by chipset 103 via bus 102. Upon powering or restarting IHS 100, processor(s) 101 may utilize BIOS 117 instructions to initialize and test hardware components coupled to IHS 100. BIOS 117 instructions may also load an operating system for use by IHS 100. BIOS 117 provides an abstraction layer that allows the operating system to interface with the hardware components of the IHS 100. The Unified Extensible Firmware Interface (UEFI) was designed as a successor to BIOS. As a result, many modern IHSs utilize UEFI in addition to or instead of a BIOS. As used herein, BIOS is intended to also encompass UEFI.

In the illustrated embodiment, BIOS 117 includes a predefined memory or memory region that may be referred to as NVM (Non-Volatile Memory) mailbox 106. In such an implementation, mailbox 106 may provide a secured storage location for use in storing workspace access policies, signatures, cryptographic keys or other data utilized to host and validate a workspace on IHS 100. In certain embodiments, the BIOS mailbox 106 may be utilized as a secure storage utilized by a remote orchestration service in order to store access policies and cryptographic keys for use in delivering and deploying a secured container on IHS 100. BIOS mailbox 106 and secured storage 120 in system memory 105 may be utilized in this manner instead of, or in conjunction with, out-of-band functions implemented by trusted controller 115.

In certain embodiments, trusted controller 115 is coupled to IHS 100. For example, trusted controller 115 may be an embedded controller (EC) that is installed as a component of the motherboard of IHS 100. In various embodiments, trusted controller 115 may perform various operations in support of the delivery and deployment of a workspace to IHS 100. In certain embodiments, trusted controller 115 may interoperate with a remote orchestration service via an out-of-band communications pathway that is isolated from the operating system that runs on IHS 100. Network interface 109 may support such out-of-band communications between trusted controller 115 and a remote orchestration service.

As described, IHS 100 may host one or more workspaces that provide access to managed resources. In some embodiments, trusted controller 115 may implement operations that support the secure transfer of data between multiple workspaces in operation on IHS 100. Trusted controller 115 may include one more memory devices that may include non-volatile and/or volatile memory components. Such memory devices may be accessible exclusively via trusted controller 115 and may thus be isolated from the software and other hardware components of IHS 100. In some embodiments, the memory of trusted controller 115 may be segregated into portions for exclusive use by workspaces, including segregated portions for exclusive use by individual workspaces. In some embodiments, trusted controller 115 may include a memory region dedicated for exclusive use as a buffer used to support transfer of data between workspaces operating on IHS 100, such as described in additional detail with regard to FIG. 4.

Trusted controller 115 may receive cryptographic information required for secure delivery and deployment of a workspace to IHS 100. In such embodiments, the cryptographic information may be stored to secured storage 121 maintained by trusted controller 115. Additionally, or alternatively, trusted controller 115 may support execution of a trusted operating environment that may support cryptographic operations used to deploy a workspace on IHS 100. Additionally, or alternatively, trusted controller 115 may support deployment of a workspace within the OS of IHS 100 via an out-of-band communications channel that is isolated from the OS and allows the workspace to communicate with a trusted agent process of the OS.

In certain embodiments, trusted controller 115 may be additionally configured to calculate signatures that uniquely identify individual components of IHS 100. In such scenarios, trusted controller 115 may calculate a hash value based on the configuration of a hardware and/or software component coupled to IHS 100. For instance, trusted controller 115 may calculate a hash value based on all firmware and other code or settings stored in an onboard memory of a hardware component, such as a network interface 109. Such hash values may be calculated as part of a trusted process of manufacturing IHS 100 and may be maintained in the secure storage 121 as a reference signature.

Trusted controller 115 may be further configured to recalculate a hash value at a later time for such a component. The hash value recalculated for the component may then be compared against the reference hash value signature in order to determine if any modifications have been made to a component, thus indicating the component has been compromised. In this manner, trusted controller 115 may be used to validate the integrity of hardware and software components installed on IHS 100. In certain embodiments, remote orchestration service 206 may verify the integrity of the trusted controller 115 in the same manner, by calculating a signature of trusted controller 115 and comparing it to a reference signature calculated during a trusted process for manufacture of IHS 100. In various embodiments, one or more of these operations supported by trusted controller 115 may be implemented using BIOS 117.

Trusted controller 115 may also implement operations for interfacing with a power adapter in managing power for IHS 100. Such operations may be utilized to determine the power status of IHS 100, such as whether IHS 100 is operating from battery power or is plugged into an AC power source. Firmware instructions utilized by trusted controller 115 may be used to operate a secure execution environment that may include operations for providing various core functions of IHS 100, such as power management and management of certain operating modes of IHS 100 (e.g., turbo modes, maximum operating clock frequencies of certain components, etc.).

In managing operating modes of IHS 100, trusted controller 115 may implement operations for detecting certain changes to the physical configuration of IHS 100 and managing the modes corresponding to different physical configurations of IHS 100. For instance, where IHS 100 is a laptop computer or a convertible laptop computer, trusted controller 115 may receive inputs from a lid position sensor 112 that may detect whether the two sides of the laptop have been latched together to a closed position. In response to lid position sensor 112 detecting latching of the lid of IHS 100, trusted controller 115 may initiate operations for shutting down IHS 100 or placing IHS 100 in a low-power mode.

IHS 100 may support the use of various power modes. In some embodiments, the power modes of IHS 100 may be implemented through operations of trusted controller 115 and/or the OS of IHS 100. In various embodiments, IHS 100 may support various reduced power modes in order to reduce power consumption and/or conserve battery power when IHS 100 is not actively in use, and/or to control a level of performance available to the user by increasing or decreasing a maximum operating clock frequency of a component of IHS 100 (e.g., processor(s) 101).

In some embodiments, an IHS 100 may not include all of the components shown in FIG. 1. In other embodiments, an IHS 100 may include other components in addition to those that are shown in FIG. 1. Furthermore, some components that are represented as separate components in FIG. 1 may instead be integrated with other components. For example, in certain embodiments, all or a portion of the operations executed by the illustrated components may instead be provided by components integrated into processor(s) 101 as systems-on-a-chip.

FIG. 2 is a diagram depicting an example of method 200 for secure transfer of data between workspaces operating on an IHS 100. For sake of illustration, method 200 has been split into three phases: workspace initialization phase 200A, workspace orchestration phase 200B, and workspace termination phase 200C. During initialization 200A, user 201 (e.g., an enterprise user, a user of personal IHS) operates an IHS 100 (e.g., a desktop, a laptop, a tablet, a smart phone, etc.) such as described with regard to FIG. 1 within physical environment 202 (e.g., any type of environment and its associated context, including physical location, geographic location, location within a particular facility or building, detected networks, detected xR signals, time of day, proximity of the user, individuals in the vicinity of IHS 100, etc.).

Method 200 starts with an action by user 201 at a launch point 203 that may be, for example, a corporate launch point provided by an employer of user 201, a launch point 203 provided by the manufacturer of IHS 100, or a launch point provided as a service to user 201 by a third-party. Particularly, user 201 operates IHS 100 to access launch point 203 that is provided, for example, in the form of a web portal, a portal application running in the operating system of IHS 100, a special-purpose portal workspace operating on IHS 100, or the like. In various implementations, launch point 203 may include Graphical User Interface (GUI) elements representing different software applications, data sources and/or other resources that the user may desire to execute and/or manipulate. In various embodiments, launch point may provide a graphical, textual and/or audio interface by which data or other resources may be requested by a user 201. As such, an authenticated user 201 may be provided a launch point that provides visibility as to one or more software applications and an aggregation of user's data sources available across all of their datastores (e.g., local storage, cloud storage, etc.).

As described in additional detail below, workspaces for providing user 201 with access to requested data or other resources may operate using a local management agent 332 that operates on IHS 100 and is configured to interoperate with workspace orchestration service 206. In various embodiments, launch point 203 may be provided in the form of a portal (e.g., a webpage, OS application or special purpose workspace) that allows user 201 to request access to managed resources via IHS 100. In various embodiments, launch point 203 may be hosted by remote workspace orchestration service 206, local management agent 332 on IHS 100, or any suitable combination thereof. Examples of launch point 203 technologies may include WORKSPACE ONE INTELLIGENT HUB from WMWARE, INC., and DELL HYBRID CLIENT from DELL TECHNOLOGIES INC., among others.

Initialization phase 200A begins when user 201 chooses to launch an application or access a data source managed by the workspace orchestration service 206. In response to an access request issued by user 201 (e.g., the user “clicks” on an icon of launch point 203), local management agent 332 of client device 100 collects initial security and productivity context information at 204. The security context information may include attributes indicating a security risk associated with: the data and/or application being requested, a level of risk presented by the user 201, the hardware utilized by the IHS 100, the logical environment of IHS 100 in which a workspace will be deployed to provide access to the requested data and/or application, and the physical environment 202 in which IHS 100 is currently located.

Accordingly, in this disclosure, the term “security context” generally refers to data or other information related to a security posture in which a workspace will be deployed and utilized, where the security posture may be based on the, user, IHS 100, data to be accessed via the workspace, and/or environment 202. A security context may be quantified as a security risk score in support of evaluations of the level or risk associated with providing user 201 access to requested data and/or application while using IHS 100 in the particular context. A “security risk score” generally refers to a numerical value usable to score, quantify, or measure various security characteristics of the security context associated with a request. A risk score may be an aggregate score associated with the overall security risk context, whereas a “risk metric” may be a measurement of risk for a sub-category of some part of the security context. Security attributes that may be used in the calculation of a security risk score for a particular security context may include, but are not limited to: a classification of the requested data source and/or application, authentication factors used to identify user 201, the location of IHS 100, a role or other group classifications associated with user 201, validation of networks in use by IHS 100, type of network in use by IHS 100, network firewall configurations in use by IHS 100, indicators of attack (IoA), indicators of compromise (IoC) regarding IHS 100 or a resource being requested by user 201, patch levels associated with the operating system and other applications in use on IHS 100, availability of encryption, type of available encryption, access to secured storage, use of attestable hardware by IHS 100, supported degree of workspace isolation by IHS 100, etc.

The term “productivity context” generally refers to user productivity associated with a workspace, user, IHS, or environment. A “productivity score” generally refers to an index usable to score, quantify, or measure various productivity characteristics of a productivity context. Examples of productivity context information include, but are not limited to: the hardware of the IHS, the software of the IHS, including the operating system, power states and maximum clock frequencies of selected components of the IHS, peripheral devices coupled to the IHS, either permanently or temporarily, networks available to the IHS and the performance characteristics of those networks, software installers available on the IHS, etc.

Initial productivity and security targets for a workspace may be calculated based on the context of user's 201 actions combined with the productivity and security context in which the workspace will operate. The productivity and security targets may also be based on user's 201 behavioral analytics, IHS 100 telemetry and/or environmental information (e.g., collected via sensors 112). In some cases, at 205, a local management agent operating on IHS 100 may calculate initial security and productivity targets based upon the collected security and productivity context. In other cases, remote workspace orchestration service 206 may calculate security and productivity targets.

As used herein, the term “security target” generally refers to the attack surface presented by a workspace that is created and operated based on a workspace definition, while the term “productivity target” generally refers to the productivity characteristics of a particular workspace definition. Examples of a productivity target include, but are not limited to: type of data or data source available to user 201, minimum latency of a workspace, etc. Conversely, attributes that may be used to characterize a security target may include, but are not limited to: a minimum security score for a workspace, a minimum trust score of IHS 100, authentication requirements for user 201 (e.g., how many authentication factors are required, frequency of re-authentication), minimum level of trust in the network utilized by a workspace, required isolation of a workspace from IHS 100, the ability to access browser within a workspace, the ability to transfer data between workspaces, the ability to extend a workspace, etc.

Moreover, the term “workspace definition” generally refers to a collection of attributes that describe aspects a workspace that may be assembled, created, and deployed in a manner that satisfies a security target (i.e., the definition presents an attack surface that presents an acceptable level of risk) and a productivity target (e.g., data access, access requirements, upper limits on latency, etc.) in light of the security context (e.g., location, patch level, threat information, network connectivity, etc.) and the productivity context (e.g., available device type and performance, network speed, etc.) in which the workspace is to be deployed. A workspace definition may enable fluidity of migration of an instantiated workspace, since the definition supports the ability for a workspace to be assembled on any target OS or IHS that is configured for operation with the workspace orchestration service 206.

In describing capabilities and constraints of a workspace, a workspace definition 208 may prescribe one or more of: authentication requirements for user 201, containment and/or isolation of the workspace (e.g., local application, sandbox, docker container, progressive web application (PWA), Virtual Desktop Infrastructure (VDI), etc.), primary applications that can be executed in the defined containment of the workspace to enable user 201 to be productive with one or more data sources, additional applications that enhance productivity, security components that reduce the scope of the security target presented by the productivity environment (DELL DATA GUARDIAN from DELL TECHNOLOGIES INC., an anti-virus, etc.), the data sources to be accessed and requirements for routing that data to and from the workspace containment (e.g., use of VPN, minimum encryption strength), workspace capabilities to independently attach other resources; etc.

In some implementations, workspace definitions may be based at least in part on static policies or rules defined, for example, by an enterprise's Information Technology (IT) personnel. In some implementations, static rules may be combined and improved upon by machine learning (ML) and/or artificial intelligence (AI) algorithms that evaluate historical productivity and security data collected as workspaces are life cycled. In this manner, rules may be dynamically modified over time to generate improved workspace definitions. If it is determined, for instance, that a user dynamically adds a text editor every time he uses MICROSOFT VISUAL STUDIO from MICROSOFT CORPORATION, then workspace orchestration service 206 may autonomously add that application to the default workspace definition for that user.

Still with respect to FIG. 2, during orchestration 200B, the initial security and productivity targets are processed and/or reconciled against resources, device capabilities, and cloud services available, etc., to produce a workspace definition at 208. As described, a workspace definition may specify capabilities and constraints of a workspace, such as: runtime security requirements of the workspace containment (e.g., such as isolation from the OS of IHS 100 or from certain hardware of IHS 100), the use of reference measurements to attest to the integrity of the workspace while in operation, applications to be provided for operation within the workspace, aggregation of resources available via the workspace, access configurations (e.g., virtual private network or “VPN”), etc.

The initial workspace definition may then then utilized by automation engine 302 of workspace orchestration service 206 to coordinate the assembly 209 and instantiation 210 of a workspace on an appropriate platform—e.g., on the cloud or on IHS 100—based on the security and productivity contexts in which the workspace will operate. In cases where a workspace is cloud-hosted, the automation engine 302 may assemble and instantiate a remote workspace that may be accessed via a secure connection established via a web browser or other web-based component operating on the IHS 100. In some embodiments, automation engine 302 may resolve configuration conflicts between a workspace definition and the user's inputs in the operation of a workspace.

In this manner, multiple distinct workspaces may be assembled and instantiated for providing access to managed resources via IHS 100. For instance, a first workspace may be initiated through selection of a managed resource, such as a protected data source, that is presented to the user 201 via launch point 203. The first workspace may operate in full or in part on IHS 100, with parts of the first workspace possibly operating remotely from IHS 100 in scenarios where user 201 is accessing a high-risk managed resource and/or where the security protections offered by IHS 100 are inadequate. A second workspace may be initiated through selection of another managed resource that is presented to the user 201 via launch point 203. The second workspace may similarly operate in full or in part on IHS. As described in additional detail with regard to FIG. 4, data may be transferred securely between the first and second workspaces even though each of the workspaces have been assembled and instantiated for providing access to different managed resources that are associated with different risk levels, thus resulting in different security protections offered by each of the workspaces.

An instantiated workspace is operated by user 201 at 211, and new productivity and security context information related to the behavior or use of data is generated at 212. This operation of a workspace may result in a change or new classification of data based upon what user 201 has done, accessed, and/or created, thus resulting in a change to the security context of the workspace. To the extent the user's behavioral analytics, device telemetry, and/or the environment has changed to a quantifiable degree, these changes in security context may serve as additional input for a reevaluation of the security and performance targets at 207 by automation engine 302. Additionally, or alternatively, new workspace context, security target, and/or productivity target may be now measured against the initial targets, and the result may cause automation engine 302 to produce a new workspace definition at 208, if appropriate.

Particularly, if the instantiated workspace(s) have parameters that fall outside of the range of the target indexes such that a difference between additional or updated context information and the initial or previous context information is scored below a threshold value, automation engine 302 may process the assembly of modifications to an existing workspace and deploy such modifications at 210. Conversely, if the difference between the additional or updated context information and the initial or previous context information is scored above a threshold value, automation engine 302 may generate a new workspace at 210. Session data metadata and context may be preserved by data aggregation engine 336, and session data may be restored as applicable.

Additionally, or alternatively, method 200 may terminate or retire the initial or previous workspace at 213, as part of termination phase 200C. In some cases, user action may initiate the termination process (e.g., user 201 closes the application being used to access the managed resources) and/or termination may take place automatically as part of an adjustment in workspace definition (e.g., the isolated environment is instructed to terminate by automation engine 302). Still as part of termination phase 200C, workspace resources of IHS 100 and/or at workspace orchestration service 206 may be released.

As such, in various embodiments, method 200 enables secure user productivity even when a workspace operates on an IHS or cloud platform that is not under direct management. Method 200 also provides for dynamic or adaptive configurations and policies allowing for the best possible user experience while maintaining appropriate level of security. In some cases, the definition of a productivity environment and access requirements may be selected based upon productivity and security dependencies and targets, and the definition of capabilities related to the workspace may be adaptive in nature. Particularly, workspace definition attributes may be dynamically selected based upon historical productivity and security information, based upon each individual user or group's behavior.

FIGS. 3A and 3B show a diagram of an example of system components 300A and 300B (collectively referred to as “system 300”) configured according to various embodiments to support secure transfer of data between workspaces 331A-N operating on an IHS 300B. Particularly, component system 300A comprises workspace orchestration service 206, and it may include one or more IHSs remotely located and/or networked having program instructions stored thereon that, upon execution, cause the one or more IHSs to perform various workspace orchestration operations described herein, including, but not limited to: the dynamic evaluation of security and productivity targets based upon updated context information received from IHS 100, the calculation of risk scores, productivity scores and other productivity and security metrics based on ongoing collection of context information, the generation of workspace definitions, and the assembly of one or more files or policies that enable the instantiation of a workspace in accordance with a workspace definition at a cloud service and/or IHS 300B.

Component 300B comprises IHS 100 having program instructions stored thereon that, upon execution, cause IHS 100 to perform various local management operations described herein, including, but not limited to, the collection of productivity and security context information, the calculation of productivity scores and/or risk scores, the instantiation, execution, and modification of a workspace based upon files or policies, such as workspace definitions, received from workspace orchestration service 206, etc.

Workspace orchestration service 300A and IHS 300B may be coupled to each other via any suitable network technology and/or protocol that allows workspace orchestration service 300A to be remotely provided with respect to IHS 300B. As described with regard to FIG. 1, an IHS according to embodiments may include a component such as a trusted controller that may support certain secure, out-of-band communications that are independent from the operating system of IHS 100. In some embodiments, such a trusted controller may be configured to support deployment and operation of workspaces on 300A and to report changes in context information to the workspace orchestration service 300A.

As illustrated in component 300A of FIG. 3A, workspace orchestration service 206 may include a number of sub-components that support deployment and ongoing evaluation and adaptation of workspaces on an IHS 300B. Embodiments of the workspace orchestration service 300A may include systems that may support: web services 306, manufacturer integration 317, and analytics 323. Moreover, web services 306 may comprise application services 301 and user interface (UI) and automation services 302.

Analytics services 323 may be configured to receive and process context information from IHS 300B, both during initial configuration of a workspace and in ongoing support of workspaces, and to provide that information, along with any analytics generated, to context logic 303 of application services 301. Based on information collected during the deployment and ongoing support of workspaces, support assistance intelligence engine (SAIE) 324 may be configured to generate and/or analyze technical support information (e.g., updates, errors, support logs, etc.) for use in diagnosing and repairing workspace issues. Workspace insights and telemetry engine 325 may be configured to analyze and/or produce device-centric, historical, and behavior-based data (e.g., hardware measurements, use of features, settings, etc.) resulting from the operation of workspaces. Workspace intelligence 326 may include any suitable intelligence engine for processing and evaluating context data in order to identify patterns and tendencies in the operation of workspaces and in the adaptation of workspaces based on context changes.

As illustrated, an application services 306 system of the workspace orchestration service 300A includes an UI and automation services 302 system that may include context logic or engine 303, classification policy 304, and condition control module or engine 305. Context logic or engine 303 may support processing of context information in making risk assessments (e.g., evaluating the risk associated with requests by the user against the context of the user's behavior, history of the user's IHS, capabilities of the user's IHS, and environmental conditions). As described, an IHS may support multiple workspaces simultaneously. In certain embodiments, context logic 303 may support determinations of a risk associated with transfer of data between workspaces, where the risk may be determined based on the change in security context that would result from permitting a particular portion of data to be transferred from a source workspace to a destination workspace. Classification policy 304 may include administrator and machine-learning defined policies describing risk classifications associated with different security contexts, such as risk classifications for specific data, locations, environments, IHSs, logical environments, or user actions (e.g., use of high-risk data requires use of a workspace definition suitable for use with a risk score above a specific value). For instance, if transfer of data is to be permitted to a destination workspace, classification policy 304 may determine requirements for an updated workspace definition for the destination workspace that will provide adequate protections for providing access to the copied data. Condition control module or engine 305 may include intelligence providing automated decision making for appropriately aligning risk and context. In some cases, condition control module or engine 305 may dynamically deploy a solution to address any detected misalignment of risk and context. For instance, upon requesting access to a highly classified data source that results in a significant increase in risk score, the condition control engine may select workspace definition modifications that implement security procedures that are suitable for the higher risk score. For instance, in the scenario where data is being copied from a source workspace to a destination workspace, condition control 305 may determine whether a particular change in the security context of the destination workspace that would result from permitting the transfer (e.g., a 10% increase in the risk score) warrants a modification of the security target of the destination workspace. In certain embodiments, condition control 305 may additionally initiate the updates required to push an updated workspace definition to the destination workspace, where the updated definition includes security procedures determined to sufficiently improve the security target of the destination workspace based on the change in risk context that would result from permitting the transfer of data.

Application services 301 may include a group of web services 306 called on by UI and automation services 302 to support various aspects of the orchestration of workspaces. Particularly, web services 306 may include application and workspace services 307 that may assemble and package applications for deployment in a workspace (e.g., a “.msix” file packaged and deployed to a MICROSOFT HYPER-V container). In some embodiments, a workspace definition may be used to specify whether a user will be provided access to an application in this manner. Web services 306 may also include a tenant subscription module 308, that performs dynamic configuration of an IHS and deployment of the described workspace orchestration services at the point-of-sale (POS) of an IHS. A license tracking module 309 may be used to maintain and track license information for software, services, and IHSs. An access control module 310 may provide top level access controls used in controlling access to data and applications by authorized users. A Unified Endpoint Management (UEM) module 311 may be configured to support the described orchestration of workspaces on various different IHSs that may be utilized by a particular user.

Web services 306 that may be used in support of workspaces may further include resource provisioning services 312 for configuring an IHS or workspace with secrets/credentials necessary to access specific resources (e.g., credentials for use of VPNs, networks, data storage repositories, workspace encryption, workspace attestation, and workspace-to-device anchoring). In some cases, resource provisioning services 312 may include secrets provisioned as part of a trusted assembly process of IHS 300B and, in some instances, associated with a unique identifier 348 of the IHS 300B. Web services 306 may also include an authorization/token module that provides identity functions and may connect to various authentication sources, such as, for example, Active Directory. Endpoint registration module 314 may be configured to register IHSs and/or workspaces with a management service that tracks the use of the described workspace orchestration. In some scenarios, a directory services 315 module may be configured to provide active directory services (e.g., AZURE ACTIVE DIRECTORY from MICROSOFT CORPORATION). Device configuration services 316 enable central configuration, monitoring, managing, and optimization of workspaces that in certain contexts may operate remotely from an IHS and may only present the user of the IHS with an image of the workspace output. In cooperation with resource provisioning services 312, device configuration services 316 may also handle secret creation and IHS configuration, and it some cases, may be out-of-band capable and handle selected operations to the endpoint.

Still referring to FIG. 3A, manufacturer integration components 317 communicate with application services 301 and client IHS 300B to provide features that are usable during workspace evaluation and instantiation, where these features are based upon information available to the manufacturer of client IHS 300B. For instance, certificate authority 318 may include an entity that issues digital certificates that may be used in validating the authenticity and integrity of the hardware of IHS 300B. Identity service module or engine 319 may be configured to manage the user's or owner's identity as well as brokering identification for use of customer directory 322. Order entitlement module or engine 320 may be responsible for managing the entitlements purchased as well as the associated issued certificates signed by 318. Ownership repository 321 may manage user entitlements associated with IHSs and their ownership and may provide support for users transferring ownership of an IHS and conveying the entitlements associated with that IHS. In certain scenarios, ownership repository 321 may use this transfer of ownership to decommission the secrets associated with the entitlements embedded in the IHS. Customer directory 322 may be configured to authenticate and authorize all users and IHSs in a network, such as assigning and enforcing security policies for all IHSs and installing or updating software (in some cases, customer directory 322 may work in cooperation and/or may be the same as directory services 315).

Referring now to IHS 300B of FIG. 3B, in some embodiments, IHS 300B may be configured to operate a local management agent 332 that may run within a secure execution environment 345 hosted by a trusted controller 341, such as trusted controller 115 of FIG. 1. In other embodiments, the local management agent 332 may operate as a trusted and attestable process of the operating system of IHS 300B. In some embodiments, local management agent 332 may include a workspace engine suitable for instantiating and managing the operation of one or more workspaces 331A-N on IHS 300B. As described, the capabilities of a workspace may be modified based on changes in the productivity and security contexts in which the workspace is operating. Accordingly, the workload(s) in each of the workspaces 331A-N may be hosted in a public cloud, a private cloud, a specific server, or locally hosted on IHS 300B, depending on the context in which the workspace is operating. These allocations of workspace computing for each particular workspace 331A-N may be prescribed by the workspace definition that is used to build and operate each workspace. As described, the workspace definition may be created by workspace orchestration service 206 based upon context information provided by IHS 300B, security targets for each workspace 331A-N, and productivity targets for each workspace 331A-N.

In some embodiments, local management agent 332 may be configured to host, launch, and/or execute a workspace hub 327 that provides a launch point 203 by which user's initiate workspaces through the selection of managed data and resources. In various embodiments, launch point 203 may be an agent, application, special-purpose workspace or web portal the provides an interface by which a user may select from an aggregated collection of data sources, applications, calendars, messages or other managed information or resources that are available to the user of IHS 300B via operation of a workspace as described herein. In various embodiments, the launch point 203 may be provided in the form for textual, graphical and/or audio user interfaces that allow a user of IHS 300B to select available data and/or resources. In some embodiments, workspace hub 327 may utilize a local environment management module 328 in providing the workspace interface that is presented to the user on IHS 300B and doing so in a consistent manner across workspaces 331A-N. Workspace hub 327 may also include a local intelligence logic or engine 329 used to support modeling the use of IHS 300B in order to improve characterization of the actual risk associated with a risk context. User authentication and access control operations may be performed by a local identify module 330 that may interface with trusted controller 341 in providing user authentication.

In some cases, each instantiated workspace 331A-N may be an environment that provides a user with access to requested data or applications, where the environment may be isolated in varying degrees from the hardware and software of IHS 300B based on the security context and productivity context in which each workspace 331A-N is operating. In some instances, the selection of a data source or resource that are available to user via launch point 203 may result in launching a new workspace. For instance, if a user launches a browser through selection of an icon displayed by launch point 203, a new workspace may be created and launched according to a workspace definition that has been selected for providing the user access to a web browser in the security and productivity contexts in which the request has been made. In a scenario where the user double clicks on a confidential presentation file available from a data source that is provided by launch point 203, an additional workspace may be instantiated with a presentation application providing access to the requested presentation file, where this new workspace is created based on a workspace definition that provided appropriate security for access to the confidential presentation). In other instances, a selection of the presentation file by a user may result in the presentation being made available through the existing workspace, in some cases using the existing workspace definition and, in other cases, using a workspace definition that has been modified to support the requested access to the confidential presentation file.

Although workspaces 331A-N supported by IHS 330B may each be isolated to varying degrees from the hardware and/or software of IHS 300B and from each other, a user of IHS 330B may expect to be able to operate the multiple workspaces 331A-N in a manner that allows content to be transferred between the different workspaces 331A-N. For instance, a user may select a portion of the data displayed in workspace 331A and utilize operating system or other workspace functions to copy the data for copying to workspace 331B. In some scenarios, workspace 331A may be instantiated to provide a user with access to protected data associated with a high risk. In light of the resulting high-risk security context, the workspace definition of workspace 331A may include security constraints that include protections that provide secure access to the high-risk protected data. Allowing the user to copy this protected data to another workspace 331B may result in exposing the protected data since workspace 331B may have been constructed to support a lower risk security context and thus may not enforce sufficient security constraints to protect the copied data. As described in additional detail in regard to FIG. 4, IHS 300B may implement procedures for monitoring attempts to copy or transfer data between workspaces 331A-N and evaluating whether the security provided by the destination workspace is sufficient.

In various embodiments, a local management agent 332 may operate in full or in part on a secure platform 345 hosted by trusted controller 341 that operates independent from the operating system of IHS 300B. In some embodiments, all or part of local management agent 332 may operate as trusted components of the operating system of IHS 300B. In some embodiments, all or part of local management agent 332 may operate as trusted components of the operating system of client IHS 300B. To execute the various operations described herein, local management agent 332 may include a command monitor 334 configured to provide instrumentation to receive commands from workspace orchestration service 300A and thus enable access to IHS 300B. Local management agent 332 may also include telemetry module 335 that may be configured for communicating collected information to the workspace orchestration service 300A, including reporting changes in context that may warrant adjustments to workspaces 331A-N. Data aggregator 336 may track all of the data source and other resources (e.g., applications, local or cloud-based services) that may be provided to the user via a workspace.

In some embodiments, local management agent 332 may support functions that allow portions of data to be transferred between individual workspaces 331A-N. For instance, in certain embodiments, local management agent 332 may support workspaces 331A-N that operate in isolation from the operating system of IHS 330B. In such instances, workspaces 331A-N may be operated by local management agent 332 using isolated resources, such as trusted controllers and exclusive memory regions. In some embodiments, local management agent 332 may support transfer of data between workspaces via a buffer that may be an isolated memory region supported by local management agent 332. In some embodiments, the data transfer buffer utilized by local management agent may be a region of memory supported by a trusted resource, such as the trusted controller 115 described with regard to FIG. 1.

Local management agent 332 may utilize a resource manager module 337 that is configured to manage access to data, network configuration, such as for VPNs and network access, identity information, access control, and resource provisioning services. In certain embodiments, resource manager module 337 may be configured to identify hardware resources of IHS 300B that are not currently in use by one or more of the workspaces 300A-N. For instance, certain hardware components of the IHS 330B, such as a camera or microphone, may be disabled or otherwise unavailable for use by workspaces. Upon identifying such components and gaining authorization to use them in support of workspaces 331A-N, the security of the workspace may be improved (e.g., for use in biometric authentication of the user of IHS 330B) in a manner that allows resources to be used to improve the productivity of workspaces 331A-N.

A security module 338 of IHS 300B may be configured to provide various security services. A BIOS interface 339 may provide a secure BIOS interface used for accessing and managing credentials in secure object storage. A BIOS analytics module 340 may be configured to perform forensic services for BIOS telemetry and health assessments. A persistence module 346 may be configured to support persistence of applications entitled at a POS or assigned by administrators and supported with required license tracking. Workspace attestation module 333 may provide a platform centric service layer on top of a container engine provided by local management agent 332 and may be used to measure and attest workspaces 331A-N in any suitable manner defined or orchestrated by condition control 305.

As part of secure platform 345, native management module 347 may be configured to enable an out-of-band (OOB) management interface with workspace orchestration service 206, where this OOB interface operates independent form the OS of IHS 300B. In some embodiments, the 00B management interface supported by native management module 347 may be utilized by the device configuration services 316 of the workspace orchestration service to access the secure platform services 345 of IHS 300B.

Digital device ID module 348 may provide a unique, unspoofable, cryptographically bound identifier. In embodiments supporting a secure platform 345, secure embedded controller 341 may be a hardened hardware module that may include a root of trust module 342 configured as a trusted data store and, in some cases for cryptographic processing, that may be trusted within a cryptographic system. A device attestation service 343 may be configured to perform device assurance and trust services (e.g., secure BIOS and secure boot, etc.). A secure object store 344 may be provided that is configured to lock and access keys, hashes, and/or other secrets in an EC and/or trusted platform module (TPM).

In some scenarios, IHS 100 may be provisioned by a manufacturer that also controls manufacturer integration components 317, workspace attestation module 333 may operate in conjunction with secure object store 342, authenticated BIOS module 339, and/or digital device identity module 348, etc., to further secure and/or control productivity features available in any of workspaces 331A-N based upon hardware devices and settings unique to IHS and/or designed specifically by that manufacturer.

To further illustrate how the systems and methods described herein operate to modernize workspace and hardware lifecycle management in an enterprise productivity ecosystem, three non-limiting use-cases or examples are discussed in turn below.

Use-Case A

In use-case A, a given user may request access to a protected data source on the enterprise's premise using a corporate-owned and imaged notebook, such configured as described with regard to IHS 100 of FIG. 1 and client IHS 300B of FIG. 3.

In response to the request, a local management agent 332 operating on the user's notebook retrieves information describing the current context and calculates security and productivity targets based on the determined context. In this use-case, the local management agent may have been installed by IT, and it may be running in the background as a service. The confidential data may be associated with the local management agent on the local machine, based on file classification (e.g., file metadata/type/properties/permissions, folder location, encrypted region, etc.). Moreover, the local management agent may continuously collect current context information and send it to the orchestration service for use in scoring the risk and productivity of the workspace (this may also be done at the time of the user's access request or indication of intent).

When the user selects the confidential data, such as via a selection via the OS of the notebook, the local management agent notifies the workspace orchestration service of the request and for a workspace definition for a workspace by which the user may be provided access to the confidential data.

In this example, the workspace orchestration service may score an overall security risk to have a value of “2,” using a weighed, machine learning, or artificial intelligence algorithm, based upon the following context information or inputs, each of which is also given as a risk metric based upon a selected policy: locale: 1 (safe locale); user persona: 1 (known high-confidence in a reasonably sophisticated user classification—a user whom historically does not click on phishing emails); network risk: 1 (low risk because of on premise, wired connection detected); device risk: 1 (high level of control because of corporate owned/managed platform, known versions, security features enabled, etc.); regulatory: 1 (based on user, data, location combinations—e.g., No restrictions with respect to General Data Protection Regulation or “GDPR,” Health Insurance Portability and Accountability Act “HIPAA,” Payment Card Industry “PCI,” technology export, etc.); and data type: 8 (a confidential datafile is being requested).

The workspace orchestration service may also calculate a productivity score to have a value of “9,” using a weighed, machine learning, or artificial intelligence algorithm, based upon the following context information or inputs, each of which is also given as a resource metric based upon a selected policy: locale: 10 (office); user persona: 9 (a “skilled” classification based upon advanced compute tasks, proficiency, and/or speed); network speed/latency: 10 (fast, wired, Gigabit Ethernet, or direct to internal network); device performance: 8 (fast, expensive CPU, memory, graphics, but storage only needs—e.g., <10 GB); and data type: 10 (the local, confidential file is easy to read/write with low latency and high performance on local storage).

Second, based upon the security score and/or context information, the workspace orchestration service builds a workspace definition file having any suitable structure with workspace definition attributes in a machine-readable format (e.g., JSON name-value, XML structured, etc.). In this example, the security target may be deemed to have a value of “1” based upon a combination of attributes values representing loads, needs, or demands on security controls and containment features that may include: threat monitoring: 1 (low demand); threat detection: 1 (low demand); threat analytics: 1 (low demand); threat response: 1 (low demand); storage confidentiality: 2 (low); storage integrity: 2 (low); network confidentiality: 1 (low); network integrity: 1 (low); memory confidentiality: 1 (low); memory integrity: 1 (low); display confidentiality: 1 (low); display integrity: 1 (low); user authentication: 1 (low, basic password is fine, non-multifactor authentication or “MFA,” no session expiration); IT administrator scope: 1 (administrator manages remotely but does not need heavy remediation software; and regulatory compliance: 1 (no GDPR, No HIPAA, no PCI, no tech export restriction, etc.).

Based upon the productivity target and/or context information, a productivity target for the workspace definition may be deemed to have a value of “9” (defining a high-quality, responsive user experience) based upon a combination of attribute values representing productivity requirements as follows: local storage: 7 (partial hard drive control, some storage reserved for IT load); CPU access: 10 (unlimited); local graphics: 10 (unlimited); and application stack: 10 (can use applications, install applications that the user needs, give them administrator rights, etc.).

Third, after the workspace definition is complete, the workspace orchestration service and the local management agent may assemble the workspace and instantiate it for the user. For example, the local management agent may receive definition files (e.g., JSON, XML, etc.) from the orchestration service, and it may parse the file to implement security risk controls such as: threat monitoring: 1 (local management agent does not install threat, detection, and response or “TDR” software); threat detection: 1 (local management agent does not install TDR software); threat analytics: 1 (orchestration does not need to gather detailed telemetry from the system, OS will not be enrolled in logging); threat response: 1 (local management agent does not install security threat response agent); storage confidentiality: 2 (local management agent deploys a local file-system encryption product that the user can optionally enable on specific files as needed with right-click context menus); storage integrity: 2; network confidentiality: 1 (local management agent confirms basic firewall configuration is correct—e.g., IT GPO-controlled); network integrity: 1; memory confidentiality: 1 (local management agent confirms configuration—e.g., No SGX, TXT, or container/sandbox software deployed); memory integrity: 1; display confidentiality: 1 (local management agent confirms graphics drivers installed, privacy screen and camera optionally managed by user); display integrity: 1; user authentication: 1 (local agent confirms basic GPO password rules are configured, and met by user—e.g., number of characters, no session expiration, etc.); IT administrator scope: 1 (local agent runs with system privilege, confirms IT admin accounts are listed in local admin user group—e.g., per GPO); and regulatory compliance: 1 (local agent does not install any compliance assistance software).

After confirming the configuration, the workspace orchestration service and the local management agent may give the user access to the requested local confidential file, and the user may begin working in a newly created workspace.

Use-Case B

In use-case B, a user may request access to a confidential datafile while at a coffee shop using an open public network and an IT-managed/owned PC, such configured as described with regard to IHS 100 of FIG. 1 and client IHS 300B of FIG. 3.

First, a local management agent (332) executed by a client IHS (300B) retrieves the requested context and calculates security and productivity scores based on context. In this use-case, the local management agent may have been installed by IT, and it may be running in the background as a service. The confidential data may kept on a shared IT-managed network resource on-premises (e.g., back in a main corporate office), and the local management agent may be responsible for monitoring when this data path is requested by the user (e.g., the user hits a specific URL, IP, etc.). Moreover, the local management agent may continuously collect all current context and send it to the workspace orchestration service to assist in scoring processes later (this may also be done at the time of the user's access request or indication of intent, rather than a continuous collection).

When the user selects the desired confidential datafile, the client IHS (300B)'s OS calls the local management agent associated with the path to the confidential datafile and calls back to a remote workspace orchestration service (206) to request a workspace definition.

In this example, the workspace orchestration service may score an overall security risk to have a value of “4,” using a weighed, machine learning, or artificial intelligence algorithm, based upon the following context information or inputs, each of which is also given as a risk metric based upon a selected policy: locale: 5 (public, safe country); user persona: 5 (new user, classification data does not exist yet); network risk: 5 (medium, public but common location, wireless connection detected); device risk: 1 (high level of control, corporate owned/managed platform, known versions, security features enabled, etc.); and regulatory: 1 (based on user, data, location combinations—e.g., no restrictions with respect to General Data Protection Regulation or “GDPR,” Health Insurance Portability and Accountability Act “HIPAA,” Payment Card Industry “PCI,” technology export, etc.).

The workspace orchestration service may also calculate a productivity score to have a value of “5,” using a weighed, machine learning, or artificial intelligence algorithm, based upon context information or inputs, each of which is also given as a resource metric based upon a selected policy. For instance, security contexts inputs may include: locale: 6 (remote location but in USA major city, in a public area, non-employees are within visual/audio range of device); user persona: 5 (unknown confidence “null” classification, uses default onboarding assumptions); network speed/latency: 4 (medium, wireless but AC on shared network); and device performance: 8 (fast, expensive CPU, memory, graphics, but storage only needs ˜<10 GB).

Second, based upon the security score and/or context information, the workspace orchestration service builds a workspace definition file having any suitable structure with workspace definition attributes in a machine-readable format (e.g., JSON name-value, XML structured, etc.). In this example, a security target may be deemed to have a value of “4” based upon a combination of attributes values representing loads, needs, or demands on security controls and containment features as follows: threat monitoring: 4 (medium demand); threat detection: 4 (medium demand); threat analytics: 4 (medium demand); threat response: 4 (medium demand); storage confidentiality: 4 (medium); storage integrity: 9 (high); network confidentiality: 5 (medium); network integrity: 2 (low); memory confidentiality: 4 (medium); memory integrity: 8 (high); display confidentiality: 7 (medium/high—worried about “shoulder surfers” reading data from an adjacent seat or table nearby, public location) display integrity: 2 (low); user authentication: 4 (medium, two-factor authentication using a hardware token, session expiration upon sleep, screen lock, or logout); IT administration scope: 3 (administrator can monitor, manage, and remediate remotely if the user calls them for help with IT issues); and regulatory compliance: 1 (no GDPR, No HIPAA, no PCI, no tech export restriction, etc.).

Based upon the productivity target and/or context information, a productivity target for the workspace definition may be deemed to have a value of “7” (defining a high-quality, responsive user experience) based upon a combination of attribute values representing productivity requirements as follows: local storage: 7 (partial hard drive control, some storage reserved for IT load); CPU access: 10 (unlimited); local graphics: 10 (unlimited); and application stack: 7 (can use applications, can install some IT-approved applications that the user needs, but no administrator rights, because the user cannot be trusted to install only valid/safe productivity software, but can install pre-approved IT applications as needed).

Third, after the workspace definition is complete, the workspace orchestration service and the local management agent may assemble the workspace and instantiate it for the user. For example, the local management agent may receive definition files (e.g., JSON, XML, etc.) from the orchestration service, and it may parse the file to implement security risk controls such as: threat monitoring: 5 (local management agent installs or confirms prior installation/configuration of TDR software); threat detection: 5 (local management agent installs or confirms prior installation/configuration of TDR software); threat analytics: 5 (orchestration confirms telemetry is accessible, OS will be enrolled in logging if not already enrolled); threat response: 2 (local management agent downloads but does not run remote incident response application—preparation in case incident is detected); storage confidentiality: 5 (local management agent deploys a local container technology, such as sandbox, with restricted “save” permissions such that the confidential files will not be allowed to save locally on the PC, but can be accessed as long as the session is active in memory); storage integrity: 5; network confidentiality: 5 (local management agent steps up firewall protections, disabling all unnecessary ports, and establishes a VPN back to the corporate office for protecting traffic to the local sandbox); network integrity: 5; memory confidentiality: 5 (local management agent configures sandbox container to isolate application and data from other applications/threats that may infiltrate the host OS); memory integrity: 5; display confidentiality: 7 (local management agent confirms graphics drivers installed, enforces privacy screen and uses camera to detect specific onlooker threats); display integrity: 7; user authentication: 4 (local agent confirms basic GPO password rules are configured, and met by user—e.g., number of characters, no session expiration, etc., but also adds in a requirement for hardware token to log in and again to establish network); IT administrator scope: 4 (local agent runs with administrator and remote access privilege, confirms IT admin accounts are listed in local admin user group—e.g., per GPO); and regulatory compliance: 4 (local agent installs state specific rule enforcement or monitoring software).

After confirming the configuration, the workspace orchestration service and the local management agent may give the user access to the requested local confidential file, and the user may begin working in a newly created workspace.

Use-Case C

In use-case C, a user may request access to a confidential datafile in a web hosted remote portal using a browser from Kazakhstan, while at an internet café with a borrowed/rented PC, such configured as described with regard to IHS 100 of FIG. 1 and client IHS 300B of FIG. 3, on an open WFi network.

First, a remote workspace orchestration service (332) intercepts the access request and evaluates the browser and user context, and calculates security and productivity scores. In this use-case, there is no local management agent; all that is known is the browser and any telemetry returned or garnered through the HTTP/S session. Assume, for sake of this example, that the confidential data may kept on a shared IT-managed network resource on-premises (e.g., back in a main corporate office) and that the datafile will remain there with only remote rendering/access privileges. Web-based context may be gathered through the browser session or supplied by the user. Moreover, user context may also be collected for the workspace orchestration service through alternate side-channels (e.g., travel calendar information, recent user billing activity on corporate credit card, phone call logs, and/or location data).

When the user selects the desired confidential datafile from the web browser, the back-end web server infrastructure calls back to the workspace orchestration service to request a workspace definition.

In this example, the workspace orchestration service may score an overall security risk to have a value of “9,” using a weighed, machine learning, or artificial intelligence algorithm, based upon the following context information or inputs, each of which is also scored as a risk metric based upon a selected policy: locale: 9 (Kazakhstan); user persona: 1 (user was expected to be there, the timing seems right based upon past logins, and he has a biometric watch communicator proving he is alive, himself, and located where he says he is—so that IT can always trust him); network risk: 9 (high, public and in a very obscure place); device risk: 9 (zero trust); and regulatory: 8 (based on user, data, location combinations).

The workspace orchestration service may also calculate a productivity score to have a value of “5,” using a weighed, machine learning, or artificial intelligence algorithm, based upon the following context information or inputs, each of which is also given as a resource metric based upon a selected policy: locale: 3 (internet café device without great performance); user persona: 9 (known high-confidence and “skilled” classification—advanced compute tasks, proficiency, and speed); network speed/latency: 3 (low quality—Wireless G from a long way away); and device performance: 3 (have to be able to tolerably browse web pages but based on what the service believes the capabilities will be, the service should build simple ones).

Second, based upon the security score and/or context information, the workspace orchestration service builds a workspace definition file having any suitable structure with workspace definition attributes in a machine-readable format (e.g., JSON name-value, XML structured, etc.). In this example, a security target may be deemed to have a value of “9” based upon a combination of attributes values representing loads, needs, or demands on security controls and containment features as follows: threat monitoring: 10 (high demand, to be handled on the server side); threat detection: 10 (high demand, to be handled on the server side); threat analytics: 10 (high demand, to be handled on the server side); threat response: 10 (high demand, to be handled on the server side); storage confidentiality: 10 (high demand, to be handled on the server side); storage integrity: 8; network confidentiality: 10 (high demand, to be handled on the server side); network integrity: 9; memory confidentiality: 10 (high demand, to be handled on the server side); memory integrity: 9; display confidentiality: 10 (high, “shoulder surfers” may read datafile from an adjacent seat or table nearby in a public location); display integrity: 9; user authentication: 10 (high, three-factor authentication using login, hardware token, and biometric satellite watch—session expiration and refreshes every 30 seconds); IT administrator scope: 8 (administrator may monitor, manage, and remediate remotely if the user calls them for help or anything unexpected happens); and regulatory compliance: 10 (all network traffic is securely monitored as will the data presented).

Based upon the productivity target and/or context information, a productivity target for the workspace definition may be deemed to have a value of “3” (defining a usable secure user experience primarily built for consumption and not productivity) based upon a combination of attribute values representing productivity requirements as follows: local storage: 1 (cache only); CPU access: 3 (build for limited expectations); local graphics: 3 (build for limited expectations); and application stack: 1 (web browser experience on a kiosk mode device, limited data entry capability, limited read access to need-to-know only information through VDI rendered kiosk).

Third, after the workspace definition is complete, the workspace orchestration service and remote cloud web portal (e.g., session the user logged into through the browser) may assemble the workspace and instantiate it for the user in the browser. For example, the web portal may receive definition files (e.g., JSON, XML, etc.) from the orchestration service, and it may parse the file to implement security risk controls such as: threat monitoring: 9 (data center based management agent installs or confirms prior installation/configuration of TDR software); threat detection: 9 (data center based management agent installs or confirms prior installation/configuration of TDR software); threat analytics: 9 (orchestration confirms telemetry is accessible, server hosting web server may be enrolled in logging if not already enrolled—user behavioral telemetry from side channels may also be continuously monitored for suspicious/anomalous activity); threat response: 10 (data center-based management agent sets up watchdog timer to kill session automatically without periodic check-ins from orchestration, user telemetry, and web browser); storage confidentiality: 9 (data center-based management agent builds a progressive web application that may be used to display the data through a secure TLS link—the data will be rendered but only the as-needed portions of visualization presented to the user, and nothing can be saved); storage integrity: 10; network confidentiality: 9 (route traffic through best effort to secure locations—do not allow anything except bitmap renderings through the enforceable network); network integrity: 4; memory confidentiality: 9 (web page viewer only—no data leaves the data center, no confidential input is taken from the rented PC, no keyboard input is allowed, and all input may be captured from randomized virtual keyboard using mouse click coordinates); memory integrity: 8; display confidentiality: 8 (best effort to ensure confidentiality—prompt user at least—adjustable font sizes, but defaults to small fonts, obfuscated text, etc.); display integrity: 2; user authentication: 9 (local agent confirms basic password rules are configured, and met by user—e.g., number of characters, no session expiration, etc., but also adds in a requirement for hardware token and biometric, satellite watch to log in and again to establish network, requiring frequent reconfirmation from user); IT administrator scope: 7 (data center-based remote environment); and regulatory compliance: 8 (local agent does not exist but data center-based agent monitors/blocks data not appropriate).

After confirming the configuration, the workspace orchestration service and the local management agent may give the user access to the requested rendered data, and the user may begin working in a newly created workspace.

FIG. 4 is a block diagram describing certain components of a system and steps of a process according to various embodiments for secure transfer of data between workspaces 405 and 410 operating on an IHS 400. As described, a workspace orchestration service may interoperate with a local management agent of an IHS 400 in order to deploy multiple workspaces 405, 410 that provide user 420 of the IHS 400 with access to managed resources. Each of these individual workspaces operates according to its own particular workspace definition, where the workspace definition for each workspace is selected by the workspace orchestration service 455 based on the security context and the productivity context in which the workspace will operate. One aspect of the security context associated with a workspace is the risk associated with the managed resource that has been requested. Accordingly, a significant difference in risk scores may exist between security contexts that provide access to highly protected data and security contexts that provide access to public or non-protected data. In order to support high levels of productivity in the use of both highly protected data and public data, separate requests for these types of data may result in the instantiation of separate workspaces that operate in isolation from each other. Despite the isolation between these different workspaces 405, 410, users may be provided with capabilities for copying data between the workspaces. Such capabilities may be provided via the local management agent of the IHS 400, the operating system of the IHS 400, third-party software applications running in the operating system of the IHS 400 and/or by the workspace orchestration service 455 itself.

In the embodiment of FIG. 4, the process may begin at 400 a with access to protected data 440 being provided via workspace 405 operating, in full or in part, on IHS 400. In some instances, workspace 405 may be constructed and may operate according to a workspace definition selected by the workspace orchestration service 455. The workspace definition may be selected in response to a request from user 420 for access to protected data 440 stored in a trusted data source 435. The selected workspace definition may specify various security constraints to be implemented by the workspace 405 in order to provide user 420 with secure access to the protected data 440 via IHS 400. As illustrated, the workspace definition may also provide user 420 with access to nonprotected data 445 via workspace 405. For instance, in conjunction with requesting access to protected data 440, such as protected sales information, user 420 may also request access to nonprotected data 445, such as public sales brochures. A user editing protected data 440, such as a private legal document, may also request access to nonprotected data 445, such as published judicial rulings or public statutes.

In various other scenarios, the protected data 440 made accessible via workspace 405 may include various types of information. For instance, protected data 440 may include financial information that may belong to user 420, a client of user 420 or an employer of user 420. Access to such financial information may be provided via a data access application 415, such as an accounting software application, that may be manipulated by user 420 via workspace 405 according to its workspace definition. In other scenarios, protected data 440 may include proprietary technical information, such as engineering drawings, that may be manipulated via a data access application 415, such as a CAD program, provided via the workspace 405. In other scenarios, protected data 440 may include various types of text documents, such as legal documents, medical information, sales information, strategic planning documents, personal information of users, customers, clients, etc., that may be manipulated by user 420 via an appropriate data access application 415. In order to protect such various types of protected data 440, workspace 405 may implement various security constraints. For instance, access to protected data 440 may require isolation of the workspace 405 from the operating system of IHS 400 such that workspace 405 operates from isolated portions of memory of IHS 400 or from memory of a trusted controller that is isolated from the software and other hardware of IHS 400. Other security constraints may include requirements for use of an encrypted workspace, use of encrypted transmissions by the workspace, enhanced authentication requirements, user presence and proximity requirements, etc.

As illustrated, IHS 400 may also support use of workspace 410 by user 420. Rather than provide access to protected data, workspace 410 may be constructed and may operate according to a workspace definition selected to provide access only to public data. For instance, workspace 410 may be instantiated in response to a request from user 420 for use of a web browser, where the request may be issued via a launch point. Since workspace 410 is not being used to provide access protected data, its workspace definition may specify fewer security requirements, thus supporting as much productivity as possible in use of the public data. In some scenarios, the protected data 440 may be protected from the less secure operating environment of workspace 410 by isolating workspaces 405 and 410 from each other, such as by executing the two workspaces 405, 410 in segregated portions of a memory of IHS 400.

Regardless of whether workspaces 405 and 410 are isolated from each other, users may utilize capabilities for transferring data between these workspaces. For instance, at 400 b, user 420 may utilize capabilities of IHS 400 to select and copy information displayed within the data access application 415 that is used to present protected data 440 of workspace 405. The copying of displayed information by user 420 may result in the copied information being stored to a buffer or other temporary storage supported by the operating system of the IHS 400 and/or by the local management agent that supports the deployment of workspaces 405, 410 on IHS 400. As described, in some embodiments, the buffer utilized to support transfer of data between workspaces 405, 410 may be operated by the local management agent and may utilize an isolated component, such as a trusted controller, in supporting this capability independent of the operating system of IHS 400. In certain embodiments, workspace data monitor 450 may be implemented as a limited-purpose workspace that operates in isolation from user workspaces 405 and 410. In such embodiments, the limited-purpose, isolated workspace used to implement the workspace data monitor 405 may provide a buffer for use as described herein in the transfer of data between workspaces 405 and 410. Based on the selection and copying of data by user 420, at 400 c, a copied portion 460 of the protected data 440 is stored to the buffer and, at 400 d, a copied portion 465 of the unprotected data 445 is also stored to the buffer.

Upon detecting the copying of data from workspace 405 to a buffer, at 400 e, a workspace data monitor 450 may initiate operations for classifying the copied data. As described, known mechanisms for data protection operate by evaluating permissions and security classifications that are associated with data files or data repositories. Once a portion of a data file has been copied, the protections associated with that data may no longer be available. Security procedures may be implemented that attempt to prevent copying of data from certain files to a buffer. Rather than blocking attempts to copy data between workspaces or enforcing file-level restrictions, the workspace data monitor 450 may implement procedures by which a risk associated with the copied data may be determined in order to support transfers of data between workspaces while maintaining security protections that are appropriate for protecting the data being copied from a source workspace 405 to a destination workspace 410.

In addition to selecting a portion of the data that is displayed in workspace 405 for copying, user 420 may also signal an intention to transfer the copied data to another workspace, such as workspace 410, currently operating in full or in part on IHS 400. In certain instances, user 420 may provide an indication of an intention to paste buffered data to this destination workspace 410 immediately upon copying of the data to the buffer. In other instances, after copying the data, this destination workspace 410 may be specified by user 420 after some delay. In certain instances, user 420 may signal an intention to transfer copied data that has been stored to a buffer to multiple destination workspaces.

Upon a portion of data being copied to a buffer by user 420, at 400 f, the workspace data monitor 450 may query the workspace orchestration service 455 for classification of the copied data. In scenarios where user 420 has also signaled an intended destination workspace 410 for the copied data, the workspace orchestration service 455 may be consulted for a determination regarding the suitability of the destination workspace 410 in protecting the copied data. In scenarios where user 420 has copied non-protected data 455 from workspace 405 to a buffer and signaled an intention to copy this data to workspace 410, the workspace data monitor 450, in conjunction with the workspace orchestration service 455, may determine that no security restrictions are required for protecting copied nonprotected data 465. Accordingly, at 400 i, the workspace data monitor 450 may transfer the copied portion of nonprotected data 465 from the buffer to workspace 410 for manipulation using a suitable application supported by workspace 410. In certain instances, even though no additional security constraints are required by the destination workspace 410 for use of nonprotected data 465, the workspace orchestration service 455 may determine that productivity targets cannot be met because destination workspace 410 requires an application that can be used to provide access to the portion of the nonprotected data 465. In such cases, workspace orchestration service 455 may select an updated workspace definition for the destination workspace 410, where the updated workspace definition specifies an application for supporting productive use of the copied portion of the nonprotected data 465. In this manner, the workspace data monitor 450 supports transfer of nonprotected data between workspaces 405, 410 operating on IHS 400.

As illustrated in FIG. 4, user 420 may also copy protected data 440 to a buffer with the intention of transferring the copied portion 460 of the protected data to workspace 410. In certain embodiments, the workspace data monitor 450 may identify the data copied to buffer as being a portion of a protected data file. In certain embodiments, workspace data monitor 450 may determine a risk associated with a buffered portion 465 of a protected data file based on metadata information associated with the protected data file 440. In some embodiments, the workspace data monitor 450 may transmit the copied data, along with any metadata or other file information, from to the workspace orchestration service 455 for a classification regarding the risk associated with providing access to the copied data. Whether determined by the workspace data monitor 450 or the workspace orchestration service 455, an evaluation of the security of workspace 410 may be required before allowing the copied data to be transferred from the buffer to workspace 410.

In certain embodiments, the workspace orchestration service 455 may determine an updated security context for workspace 410 that will result from transfer of the copied portion of protected data 460 to workspace 410. Based upon the updated security context that includes providing access to the portion of protected data 460, the workspace orchestration service 455 may calculate a risk score for providing access to this portion of protected data. In some embodiments, a risk for the copied data may be determined in part based on a risk classification associated with the data file 440 or data source 435 from which the data has been copied. As described, metadata may be associated with a data file 440, where this metadata may specify a risk classification (e.g., secret, top secret, confidential) associated with the data. Such metadata may also specify a source of a data file. Metadata may also specify a file type or other description of the information encoded in the file. In some scenarios, metadata may specify other users associated with the data file, such as the original author and editors of the file. Metadata may additionally or alternatively specify IHSs, workspaces or systems that have been used to provide access to a data file. In some scenarios, metadata for a data file may specify locations at which the data file was created, accessed and/or edited.

In some embodiments, workspace orchestration service 455 may utilize the provided metadata to identify additional risk factors associated with the copied data. For instance, the users associated with a file may be evaluated in order to determine a trust level with each user. Similarly the IHSs and/or workspaces that have been used to provide access to the copied data may be evaluated to determine a trust level associated with the copied data. Based on all or some of such metadata information, workspace orchestration service 455 may determine a risk associated with providing access to the copied portion 460 of the protected data. In some embodiments, this risk may be used to generate an updated security context for the destination workspace 410 in which the destination workspace provides access to the coped portion 460 of the protected data.

In some embodiments, the risk associated with copied data may be determined based on a classification of the actual data that has been copied to the buffer. A protected data file 440 may include both protected data as well as unprotected data. For instance, software source code may include highly protected technical details as well as less protected information such as headers, routine source code and special-purpose source code for scenarios such as display on non-standard displays. In other scenarios, financial documents may include highly protected financial figures as well as less protected information such as definitions and formulas used for processing the underlying data. Accordingly, the contents of the buffer storing the copied data may be evaluated using techniques such as fuzzy hashing in order to identify whether the copied data resembles high-risk protected data found in protected data 440 or instead resembles supporting data associated with a lower risk. By utilizing fuzzy hashing, the contents of the buffer may be quickly evaluated against the protected data 440 to identify a close match without requiring a computationally costly search for the exact contents of the buffered data within the protected data.

Based on the updated security context for the destination workspace 410, the workspace orchestration service 455 may then evaluate the existing workspace definition of the destination workspace 410 in order to determine whether additional security constraints are required in order to provide secure use of the copied portion of the protected data 460. If the updated security context indicates a requirement for additional security constraints, at 400 g, the workspace orchestration service 455 may provide an updated workspace definition that includes various changes to the current workspace definition for workspace 410. For instance, the workspace orchestration service 455 may generate an updated workspace definition for workspace 410 that requires encryption of the destination workspace 410, use of additional security tools (e.g., anti-virus, firewall or script-blocking tools) and/or specific software applications for use of the copied portion of the protected data 460. In other scenarios, the updated workspace definition may include prohibitions on further copying of the data. For instance, the protected data portion 460 may be copied to destination workspace 410, but may not be transferred elsewhere, such as to untrusted system 425.

As described, a workspace may be instantiated such that it operates in full or in part on an IHS. Portions of a workspace not operating locally on IHS 400 may instead operate remotely, thus providing additional isolation from an untrusted IHS. In some scenarios, providing access to protected data 440 may require that the source workspace 405 may be instantiated in a protected cloud system with minimal interfaces operating locally on IHS 400. In such a scenario, copying a protected data portion 460 to destination workspace 410 may require the same configuration. The workspace orchestration service 455 may thus select an updated workspace definition for workspace 410 in which certain operations of workspace 410 are migrated to the protected cloud resource in the same manner as the source workspace 405.

In the illustrated embodiment, the workspace orchestration service 455 determines that secured access to the copied portion of protected data 460 requires use of data access application 425 by workspace 410. Accordingly, at 400 g, the workspace orchestration service 455 provides workspace 410 with an updated workspace definition and supporting files necessary for workspace 410 to deploy the data access application 425. Upon completing the upgrading of workspace 410 in this manner, the workspace orchestration service 455 may notify the workspace data monitor 450 of the suitability of workspace 410 to receive the copied portion of the protected data 460. In certain instances, updating the destination workspace 410 in order to implement the additional security constraints specified by the workspace orchestration service 455 may require re-initialization of the destination workspace 410. In such instances, the workspace orchestration service may provide an indication of the time required to re-initialize or otherwise upgrade the destination workspace 410 in order to receive protected data 460 from the buffer. The workspace data monitor 450 may then notify the user 420 of the delay required to support the requested data transfer and may be asked to confirm whether to proceed with the reinitialization of the destination workspace 410 according to the updated workspace definition. At 400 h, the data monitor may proceed to transfer the portion of the protected data 460 from buffer to the destination workspace 410, thus providing user 420 with use of the copied portion of protected data 460 within the upgraded security environment provided by workspace 410.
